We have a new study and what does help immunity turns out is natural immunity.

And it's certainly a good thing.

This is how it gives Moto good news natural immunity at the coronavirus may last years

study suggest and we reported on this way back when about the possibility of this.

But this is a study now let's that's the headline.

Let's go beyond that.

Let's actually look at the study.

This is a study it's titled immunological memory to SARS-CoV-2 assess for up to eight

months after infection.

This was published in the journal science and it says in the current study we assess immune

memory of all three branches of adaptive immunity CD4 T cell CD8 T cell and he moral immunity

in a predominantly cross sexual study of 188 recovered COVID-19 cases extending up to eight

months post infections findings have implications for immunity against secondary COVID-19 and

thus the potential future course of the pandemic.

What did they find?

On IGG now these are the antibodies to the spike protein was relatively stable over six

plus months spike specific memory B cells were more abundant at six months than at one

month post symptom onset SARS-CoV-2 specific CD4 T cells and CD8 T cells declined with a half

life of three to five months.

And then finally it says the percentage of subject serial positive for SARS-CoV-2 neutralizing

antibody tighter is greater than or equal to 20 at six to eight months post symptom onset

VSO was nine percent.
